Question

Do humans have telocentric chromosomes?

Answer 1

Hint: A telocentric chromosome's centromere is located at one end of the chromosome. The centromere is so close to the chromosome's end that the p arms aren't visible, or are barely visible. Sub Telocentric chromosomes have centromeres that are closer to the end than the center. On a cytogenetic level, mouse chromosomes are classified as telocentric chromosomes with no evident short arm.

Complete answer :
The centromere of a telocentric chromosome is found at the end of the chromosome. There is only one arm on a telocentric chromosome. During anaphase, telomeres can stretch from both ends of the chromosome and have the shape of a “i.” Only telocentric chromosomes are found in the normal house mouse karyotype.
Telocentric chromosomes aren’t seen in humans. Because telocentric chromosomes are fragile and arise from chromosome misdivision or breaking near the centromere, they are not present in healthy humans. After a few cell divisions, they are usually gone.
Centromeres assemble at a single site per chromosome in most eukaryotes. Telocentric chromosomes (telomeres) with a terminal centromere are uncommon, although they do exist. Telomeres form when centromeres in normal chromosomes are misdivided, and their cytological stability is determined by the structure of their kinetochores.

Note :
The centromere is a constriction point in the center of chromosomes that separates them into two sections. Centromeres are made up of a complicated mix of proteins and DNA. They are required for cell division and correct chromosomal segregation. According to research, chromosomes without centromeres segregate at random and finally die in cells. Multiple centromere chromosomes, on the other hand, are prone to fragmentation.
